As for me, I think the extreme way is on surfing online. But internet is a tendency, so there are some ways:
Firstly, being cautious to stranger launch to admit, as the statics shows the instant messaging is a main way which the swindlers use to cheat people.
F,keep alert to play online. One should use an orthodox third-party payment, like Aliped or US key.
At the same time, one should not pay easily when you could not judge a web's facticity.
In, everyone should believe that there is no such thing as a free lunch. So you should be calm when you receive an email or dialing which tell you win a prize in a lottery.
